Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562764, here are decompositions:

53 + 31562711 = 31562764
137 + 31562627 = 31562764
197 + 31562567 = 31562764
263 + 31562501 = 31562764
281 + 31562483 = 31562764
491 + 31562273 = 31562764
503 + 31562261 = 31562764
521 + 31562243 = 31562764

Showing the first eight; more decompositions exist.
